Package: linux-image-amd64 Version: 6.12.90-2 Severity: normal After upgrading from 6.12.88-1 to 6.12.90-2, display mirroring (clone mode) no longer works on GNOME/Wayland. The external display is detected and works in extended mode, but mirroring cannot be activated via GNOME Settings → Displays. Reverting to 6.12.88-1 resolves the issue.
